Well take about 6% off your power everywhere because they added SAE correction (which ALLSTAR don't usually apply to RWD cars but I'll assume they did it on your graph because you asked for 400hp)... So that's about 380rwhp, then from a hub dyno you loose around 7% on top of that to a roller dyno dynamics so you are down to 355rwhp. So the same power as say a HKS GTRS on the same boost! Next we will talk about boost response, well it's not really that bad considering the size of the wheels of the turbo (the 0.63 rear housing is helping a lot it seems). About the same as a T67 or a GT3076R 0.82 rear, mind they make about 430rwhp on the same dyno without correction on so the same response as yours but around 50hp more top end! If you want to compare with my setup I make pretty much exactly the same power till 4000rpm and then a extra 150hp top end (mind you I cheat a little) So in essence you have a turbo that makes the same power as a HKS GTRS with over 1000rpm less response or a turbo that has the same response as a GT3076R but with 50hp less top end... CRAP!

show me your dyno graph and I'll show how your fine is actually crap!

GT35R in 0.86 are average turbos at best... in 0.63 they are just crap!

The video of it posted was just of a collector with 3 pipes going into each side of a T4 flange Just watched the video on youtube and didn't actually realise that it was only "50% complete" without any of the wastegate ports cut in etc

Looks exactly the same as a 6 boost t4 divided collector, just more fancy

I'm making 480rwhp on a dyno dynamics with a stock motor... Are you positively annoyed friend??

Go a TD06SL2 20g on the RB20... It will fly! It's a 3" v-band off the back of the turbo so you want it at least 3"

That's boost vs afrs curves with no power graph haha Jesus she is a laggy one!

stock

He would have been talking about 600rwhp... So 450rwkw Why would someone quote a hp flywheel figure when no one measures it in Australia!

Nice, cant wait to see the graph! Enjoy the drive

EXACTLY the same... EXCEPT for all the differences which make them different!

I think I have had my RB20 yellow jackets for around 2 years now... They are still holding more power/boost without any issues than I would imagine you will ever need with a RB20

Nice to see a big hp GTR out and getting used and abused What suspension does it have? Massive amounts of squat for a GTR

Nice power for that boost! What kind of dyno is that on?!?

Funny because I also have the dip and flat bit on my graph but it's definatly done on a 9sec ramp rate... When we did a 12sec ramp rate it also moved the graph a whole lot more left than yours moved so I don't think picking the difference is as simple as you have portrayed! Also I noticed how you are now putting on STP correction which gains a lot of power, the run below only makes 388rwkw without STP correction on.

None at all, still going as strong as the day it was installed... Yes, worth the money!

Yeah that's the one Boost is around 1.8bar dropping down to 1.5bar... I think the turbo is giving all it can give!

Usually don't drive it heaps because I have a work vehicle, maybe a few times a week! Mates R34 with similar mods but 50hp less ran 11.5 @ 128mph about a month ago so fingers crossed it goes ok Got the E85 from RPW in 205L barrel

Few tweaks in tune/boost and turning on SAE correction it made Same tune on a dyno dynamics in shootout mode 359rwkw Shows the difference different dynos can read Hopefully down the black strip dyno soon to show some decent mph

the active diff in a series 2 may be a different ratio?

Same shit different dyno

And here is a comparison of a 3076r with the same fuel, on the same dyno on the same day... Mine runs a little more boost, but this one has tomei poncams

Will have a crack down the quarter when I get back (in canada atm) I would say it should go a ten at 130+ mph if I get a decent run without being booted :-)

Went 480rwhp aka 360rwkw on a dyno dynamics roller yesterday...
